our ducks have a 10x20 run with a 10x5 roofed/enclosed area for the night with a doghouse for nesting. during the day, we open the run so they can explore the pasture that sits alongside our woods/swampy area. with all the rain we've had, we still have green grass, mud and puddling water so the ducks are having a blast. that will soon end as the temp gets more toward freezing and the snow arrives. we need to move our small "cement mixing" pool/tub to the outside of the duck's enclosure because most of the straw bedding is getting soaked. trying to decide whether we should put a drop-in heater in the small pool or save the heater for their water dish. if the ducks do not need water to swim in through the winter, that will answer the question. ideas?
